HYDRODYNAMICS OF OSCILLATING WING ON THE PITCH ANGLE
Journal Title: Вісник Національного Авіаційного Університету - Year 2017, Vol 71, Issue 2
Abstract
Purpose: research of the hydrodynamic characteristics of a wing in a nonstationary stream. Methods: The experimental studies of the hydrodynamic load acting on the wing of 1.5 elongation, wich harmonically oscillated respect to the transversal axis in the frequency range of 0.2 − 2.5 Hz. The flow speed in the hydrodynamic tunnel ranged of 0.2 − 1.5 m/s. Results: The instantaneous values of the coefficients of lift and drag / thrust on the pitch angle at unsteady flow depends on the Strouhal number.Discussion: with increasing oscillation frequency coefficients of hydrodynamic force components significantly higher than the data for the stationary blowing out of the wing.
